I wanted to make a NERDMINER solo lottery BTC mining device out of these Bitcoin weather clocks i got from GEEKMAGIC. And CHATGTP showed me how i could make it work with its specific TFT screen. need to test it + Canaan BTC heater? $250 for $0.3 a day?
if you buy an ESP32 or find one compatible here you can load up BTC solo mining lottery software , and get 1/2billion chance at 6 bitcoin...
